Embodiment
To describe illustrative embodiments of the present invention in detail below, example shows the example of illustrative embodiments of the present invention in the accompanying drawings.In whole accompanying drawing, represent identical or like as far as possible with identical label.
As shown in Figure 1, the drive signal processor 10 of display receives and comprises that respectively left-eye image and eye image to realize the input signal a1 of 3D rendering, perhaps are received in and carry out the received image signal of importing after the signal processing in the display.
When receiving received image signal a1, drive signal processor 10 generates doubly speed (double-speed) picture signal b1 and inversion driving signal b2.Doubly fast picture signal b1 obtains by making same frame frequency multiplication make it possible to drive received image signal a1 with double-speed, avoids the frame counter-rotating of the after image (after image) of display panel 30 with realization.Inversion driving signal b2 is used to be identified for the reversed polarity of frame counter-rotating.After this, the LCD plate is described as an example of display panel 30.
As the digital signal that is generated by drive signal processor 10, doubly fast picture signal b1 and inversion driving signal b2 are imported into digital-to-analog (D/A) transducer 20.D/A converter 20 generates liquid crystal driving signal c1 (it is an analog signal) and drives display panel 30 then.
Fig. 2 a to Fig. 2 e illustration the waveform of the output signal that generates by said process.Promptly, if with the frame is that unit has imported received image signal a1 to drive signal processor 10, then drive signal processor 10 generates doubly fast picture signal b1 (its cycle is half of cycle of the received image signal a1 in the frame), and generates the inversion driving signal b2 of the same signal counter-rotating that is used to make in the frame.
In received image signal a1, Reference numeral D1, D2 ... the expression respective frame image, and the respective frame image by have identical times of fast picture signal D1+, D2+ ... doubly fast picture signal b1 constitute.
By will be doubly fast picture signal b1 multiply by inversion driving signal b2 and obtain liquid crystal driving signal c1.Liquid crystal driving signal c1 by picture signal D1+, D1-, D2+, D2-... constitute, each picture signal doubles the speed of received image signal, and has opposite polarity.
Therefore, liquid crystal driving signal c1 can solve the after image problem in the LCD plate by the picture signal driving display that utilization has an opposite polarity.
In this situation, generate illumination control signal d1, and luminaire 31 can keep connecting (on) always with normal high state.
Simultaneously, 3D rendering has the received image signal that is made of left-eye image that with the frame is unit (L1, L2 etc.) and eye image (R1, R2 etc.).3D rendering generates as Fig. 3 a to the output waveform shown in the 3e by said process.
Specifically, left-eye image (L1, L2 etc.) replaces with eye image (R1, R2 etc.), shown in Fig. 3 a.The alternate images signal is generated as the doubly fast picture signal b1 of the identical times of fast signal (L1+, L1+, R1+, R1+ etc.) that comprises shown in Fig. 3 b.Doubly fast picture signal b1 is generated as liquid crystal driving signal c1 shown in Fig. 3 d by multiplying each other with the inversion driving signal b2 shown in Fig. 3 c.Liquid crystal driving signal c1 is made of reverse image signal (L1+, L1-, R1+, R1-etc.).
In this case, illumination control signal d1 is in high state all the time, makes luminaire 31 can remain on-state.
Fig. 4 show first pixel of writing display panel and last pixel time and when the frame rate of 3D received image signal a1 be 60Hz and left-eye image and eye image frame rate separately when being 120Hz in full HD (HD) (1080 pixel) LCD the liquid crystal response signal of these two pixels.
After this, in display panel, under the situation of realization 3D rendering indicating characteristic is described with this liquid crystal response signal.To this, for convenience, only show first pixel of display panel and the picture signal of last pixel, because when only the image by first pixel and last pixel shows 3D rendering in display panel, be enough to predict display characteristic.
With reference to Fig. 4, solid line is represented the liquid crystal luminance signal of left-eye image (L1, L2 etc.) in first pixel of display panel, and dotted line is represented left-eye image (L1, L2 etc.) the liquid crystal luminance signal in pixel in the end.
In addition, chain-dotted line is represented the liquid crystal luminance signal of eye image (R1, R2 etc.) in first pixel of display panel, and eye image (R1, R2 etc.) the liquid crystal luminance signal in pixel is in the end represented in double dot dash line.
More particularly, L1F represents the liquid crystal luminance signal of signal L1 in first pixel of display panel, and L1N represents the liquid crystal luminance signal of signal L1 in last pixel of display panel.
Similarly, R1F represents the liquid crystal luminance signal of signal R1 in first pixel of display panel, and R1N represents the liquid crystal luminance signal of signal R1 in last pixel of display panel.
As shown in the figure, signal L1N is after signal L1F has crossed the liquid crystal time for writing signal.Being used to of signal L1 or R1 shows that the field duration of left-eye image or eye image can be 2 times of liquid crystal time for writing signal.
With regard to the LCD attribute, when enabling the liquid crystal signal, realizing needing the response time before the full brightness, and when forbidding liquid crystal signal, also needing the response time to make the complete deepening of liquid crystal.
Therefore, as shown in Figure 5, when in LCD, realizing 3D rendering, can generate indication left-eye image interval and eye image interfering with each other crosstalking at interval.
In Fig. 5, Reference numeral RnF represents the eye image signal of previous picture intrusion left-eye image first pixel at interval.RnN represents the eye image signal of previous picture intrusion left-eye image last pixel at interval.That is, can occur in left-eye image and crosstalking of eye image signal RnF and RnN occur at interval.The left-eye image signal area of not crosstalking in the left-eye image interval only takies the part by " L " indication.
Similarly, Reference numeral L1F represents to invade by disable signal the left-eye image signal (it is activated) of eye image first pixel at interval in the left-eye image interval.L1N represents to invade the left-eye image signal of eye image last pixel at interval.The eye image signal area of not crosstalking in the eye image interval only takies the part by " R " indication.
As mentioned above, because liquid crystal response time and picture signal write time of display, the eye image signal may be invaded left-eye image at interval, and the left-eye image signal may be invaded eye image at interval.Left eye in utilizing LCD and right eye time difference are when realizing 3D rendering, because liquid crystal time for writing signal and liquid crystal response speed may produce sizable crosstalking.
For improving this phenomenon, use Fig. 2 a to the drive signal shown in the 2e when being preferably in, and when realizing 3D rendering, use following drive signal by LCD by LCD realization 2D picture signal.
That is, make left-eye image signal (L1, L2 etc.) and eye image signal (R1, R2 etc.) alternately be arranged in received image signal a1, shown in Fig. 6 a.Alternating signal is generated as the doubly fast picture signal b1 that is included in the black signal that does not have picture signal in each cycle.
Doubly the cycle of fast picture signal b1 can be received image signal a1 cycle 1/2.That is, doubly the speed of fast picture signal b1 can be the twice of the speed of received image signal a1.Yet doubly fast picture signal b1 can be the signal of 3 times, 1.5 times of received image signal a1 etc.
As mentioned above, doubly fast picture signal b1 comprises the black signal in each cycle.Although in Fig. 6 b, picture signal has the duration identical with black signal, and they can have the different duration.For example, the length of black signal can be longer or shorter than the length of left eye or eye image signal.
Therefore, L1 comprises L1+ signal and black signal at interval, and R1 comprises R1+ signal and black signal at interval.Similarly, L2 comprises L2+ signal and black signal at interval, and R2 comprises R2+ signal and black signal at interval.
That is, the cycle of inversion driving signal b2 changes after L1+ signal and R1+ signal.
Therefore, plate drive signal c1 comprises L1+ signal, black signal, R1+ signal and the black signal of one-period.According to the L2-signal, during the same length of one-period, generate reverse signal.Moreover, after one-period, generate normal signal (not reverse signal).
In drive signal c1, at interval
Operation range (active interval) when the expression drive signal writes liquid crystal, and at interval
Expression does not have to carry out writes fashionable space every (dummy interval).
Shown in Fig. 6 e, illumination control signal d is in high state all the time, makes luminaire 31 can remain on-state.
Yet, in these cases,, can carry out same function by in the black signal interval, closing luminaire 31.
That is, when generating the black signal shown in Fig. 6 d, can close illumination.Simultaneously, even when generating same doubly fast signal shown in Fig. 3 d, not generating black signal, also can be by when generating at least one doubly fast signal, closing the generation that illumination suppresses to crosstalk.
That is, shown in Fig. 6 f, even when generating same doubly fast signal not generating black signal, the also generation that can suppress to crosstalk by the illumination of in the interval that generates doubly fast signal subsequently, closing luminaire 31.
Therefore, at the established part of fast picture signal doubly, for example,, can close illumination in the part that generates doubly fast signal subsequently.In this case, in the illumination off-interval, can generate black signal or can generate doubly fast signal.
Fig. 7 shows the input time of signal of first pixel of being written to display panel among the LCD and last pixel and the liquid crystal response signal of these two pixels.
In Fig. 7, L1F represents the liquid crystal luminance signal of signal L1 in first pixel, and L1N represents the signal L1 liquid crystal luminance signal in pixel in the end.Similarly, R1F represents the liquid crystal luminance signal of signal R1 in first pixel, and R1N represents the signal R1 liquid crystal luminance signal in pixel in the end.
As can be seen from Figure 7, the interval between the liquid crystal luminance signal becomes wideer.Therefore, as shown in Figure 8, eliminated, and only kept, reduced the zone of crosstalking between left-eye image and the eye image thus significantly owing to crosstalking that liquid crystal response speed causes owing to crosstalking that the liquid crystal time for writing signal causes.
In Fig. 8, the part of being indicated by " L " is illustrated in the left-eye image signal area of not crosstalking in the left-eye image interval, and uses the part of " R " indication to be illustrated in the eye image signal area of not crosstalking in the eye image interval.As shown in the figure, significantly reduced the zone of crosstalking.
An illustrative embodiments as the 3D rendering display of realizing by said method has illustrated a kind of liquid crystal projection display (LCD, LCoS etc.) among Fig. 9.
In the projection display that can realize 3D rendering, the light that sends from light source 40 incides on the polarization beam apparatus (PBS) 60 by illuminating lens group 50.The light that incides on the PBS 60 forms image by display panel 30, and projects on the screen 90 by projecting lens 80, and wherein display panel 30 is driven by the output drive signal c1 that generates by drive signal processor 10 and digital to analog converter 20.
Output drive signal c1 drives display panel 30 by following process.
At first, drive signal processor 10 receives and comprises that respectively left-eye image and eye image to realize the input signal a1 of 3D rendering, perhaps are received in and carry out the received image signal of importing after the information processing in the display.
The same frame frequency multiplication fast at double picture signal b1 in next life of the received image signal a1 of drive signal processor 10 by making display panel 30.Black signal is between each left-eye image and each eye image of constituting a scene.
Drive signal processor 10 also generates and is used for determining that reversed polarity and cycle are the inversion driving signal b2 of left-eye image and eye image sum.
Doubly fast picture signal b1 and inversion driving signal b2 (they are the digital signals that generated by drive signal processor 10) are imported into D/A converter 20.D/A converter 20 generates liquid crystal driving signal c1 (it is an analog signal) and drives display panel 30 then.
Promptly, as shown in figure 10, the left-eye image that generates from display panel 30 has different polarization states with eye image by polarization conversion unit 70, thereby the beholder can watch 3D rendering by comprising corresponding to the left eyeglass lens L of two different polarization states and the polarising glass 100 of right eye eyeglass R.
Therefore, left eyeglass lens L by polarising glass 100 and right eye eyeglass R can independently see left-eye image and the eye image that generates from display panel 30, produce stereo-picture thus.
Simultaneously, when generating doubly fast picture signal and inversion driving signal, when generating the 2D picture signal, can generate different doubly fast picture signal and inversion driving signal with display when generating the 3D rendering signal at received image signal.
Promptly, can controlling and driving signal processor 10, when generating the 2D picture signal, being same signal fast at double picture signal in next life, and when generating the 3D rendering signal, be created on the doubly fast picture signal that comprises black signal between left-eye image signal and the eye image signal by making the received image signal frequency multiplication.
Simultaneously, when display panel 30 receives the light time that produces from luminaire 31, luminaire 31 can cut out illumination in the interval that generates black signal, and can this at interval in common times of fast picture signal of generation, and do not generate black signal.
In this case, drive signal processor 10 is preferably in to generate when generating the 3D rendering signal and has the reverse image signal that the cycle is left-eye image signal and eye image signal sum.
The LCD plate can be used as display panel 30, and display panel 30 can be applicable to use all devices of LCD plate, for example, and LCD television set, monitor etc.
The present invention has used and has comprised that black signal with the left-eye image that reduces to be caused by slow writing speed and the liquid crystal driving signal of the interference between the eye image, realizes the high-quality 3D rendering thus.
It will be apparent to those skilled in the art that, can under the situation that does not break away from the spirit or scope of the present invention, make various modifications and variations the present invention.Therefore, the present invention is intended to contain these modifications and variations that fall in claims and the equivalent scope thereof of the present invention.
